High-Temperature Insulating Film Tapes
-- Steady & Reliable Manufacturer --
Advanced Film Tapes for Extreme Thermal Insulation and Masking
Our High-Temperature Insulating Film Tapes are engineered for use in challenging thermal environments, providing reliable electrical insulation, masking, or component holding at elevated, continuous operating temperatures, often exceeding 130∘C. These tapes utilize specialized backing materials, such as Polyimide (Kapton-type), PTFE (Teflon), or high-temperature Polyester (PET), paired with silicone or high-performance acrylic adhesives. Their dimensional stability under heat is critical, ensuring they neither shrink nor degrade, maintaining dielectric strength and clean removability after high-temperature curing or processing (e.g., powder coating, wave soldering). They are essential for protecting sensitive electronic components and achieving quality finishes in high-heat industrial processes.
- Thermal Stability: Maintains integrity at temperatures up to 260∘C (Polyimide).
- Dielectric Strength: Provides reliable electrical isolation under high voltage.
- Clean Removability: Leaves no residue after exposure to thermal cycles.
Why Choose Us
Guaranteed Thermal Performance and Process Control
- No Residue or Contamination: Our silicone adhesive systems are formulated to resist transfer or decomposition, ensuring the tape peels cleanly, which is paramount in sensitive electronics manufacturing to avoid costly cleaning or rework.
- Excellent Chemical Resistance: The specialized film backings (especially PI and PTFE) are highly resistant to a range of cleaning agents, fluxes, and solvents used in industrial washing and processing.
- Consistent Dielectric Strength: Every batch is tested to confirm its ability to withstand high voltages (measured in kV/mm), guaranteeing reliable electrical insulation properties are maintained across the entire temperature range.
- Precision Slitting: Supplied with ultra-tight width tolerances, ensuring the tape provides accurate masking and insulation coverage, especially in micro-assembly environments.

Frequently Asked Questions
Frequently Asked Questions (FAQ)
- Q: What is the main factor determining whether to use a Silicone vs. an Acrylic adhesive in high-temp tapes?
- A: Silicone adhesives offer superior thermal stability (up to 260∘C) and cleaner removability after extreme heat exposure. Acrylic adhesives are more cost-effective, offer good holding power on many substrates, and are generally suitable up to 150∘C or 180∘C.
- Q: Can high-temperature tapes be die-cut into complex shapes?
- A: Yes. The PET and Polyimide films have excellent dimensional stability, making them ideal for high-precision rotary and flatbed die-cutting into intricate shapes for masking specific areas of a component or PCB.
- Q: How does SXT ensure the tape remains free of contaminants for electronic use?
- A: We use high-purity adhesives and films, and our slitting/packaging processes adhere to strict cleanliness protocols to minimize particulate contamination, ensuring the tapes are suitable for surface-mount technology (SMT) and cleanroom environments.
